WALLINGFORD, CONNECTICUT.

AUTOMATIC FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 245,885, dated August16, 1881.

Application filed May9, 1881. (No hiodel.)

To all whom it may concern:

Be it known that I, HENRY A. STEARNS, of Lincoln, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in Fire-Extinguishers; and I hereby declare that thefollowing is a full, clear, and exact description of the same. referencebeing had to the accompanying drawings, forming part of thisspecification.

[0 When distributers are secured to a system of pipes arranged todistribute water through a building so as to extinguish a fire, whetherthey are operated automatically or by hand, the impurities in the water,the oxidation of the pipes or fittings, and such impurities as areliable to be in the pipes when they are put up, will be brought from thepipes by the force of the water and lodged in the distribnlers, which,when they are perforated, as is usual, are liable to be closed in wholeor part, and are thus prevented from performing the functions for whichthey are intended, and the safety of the building is thus endangered,notwithstanding plenty of water is available. The object of thisinvention is to avoid such danger; and the invention consists inproviding the distributor with a chamber in which such impurities orsolid matter may collect Without interfering with the action of thedistributer proper.

Figure l is a view of my improved distributer; and Fig. 2 is a sectionalview of the same, shown as provided with a seal, so as to form anautomatic fire-extinguisher.

3 5 In the drawings, a is a nipple, threaded so that it can be readilysecured to the end of a pipe.

1) represents a ball that fits the end of the nipple a, and may besecured by solder fusible at a low temperature. 40

c is the distributor, perforated with small holes; and cl is thesediment-chamber, provided with one or more rows of holes, so thatthegwater may pass through the holes and allow the solid matter tosettle into the chamber 5 d. When the ball I) is used to close theoutlet a large hole is made in the bottom of the chamber (1 to receivethe ball, as is shown in Fig. 2 in broken lines; but such large hole maybe dispensed with, as there is ample room for the ball in the chamber(1.

Having thus described myinvention, I claim as new and desire to securebyLetters Patent- 1. In a fire-extinguisl'ier, the combination, with thedist-ributer, of a chamber placed below the distributor to receive thesediment, as described.

2. A perforated distributer provided with a sediment-chamber perforatedwith holes, as and for the purpose described.

3. The combination, with the nipple a and perforated distributer 0, ofthe chamber d, constructed to receive the sediment, as described.

In witness whereof I have hereunto affixed my name.

HENRY A. STE ARNS.
